CIRCULAR RIDDLE.

T 0 all whom it may concern:

Be it known that I, SILAS. H. BRAND, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Circular Riddle, of which the following is a specification.

This invention relates to screens and riddles and more particularly to circular riddles.

The object of the invention is to provide a device of this character particularly designed to be manufactured by machinery and in which the metal fabric and the finishing hoop can be fastened to the body of the riddle in one operation.

Another object is to provide a riddle in which a number of comparatively small staples can be utilized for holding the metal fabric in position, said staples being merely large enough to extend through the finishing hoop and the fabric, there being a few larger staples utilized for securing the finishing hoop to the body of the riddle and which are clenched within the body and extend over a desired number of smaller staples, this construction greatly reducing the cost of the riddles as compared with those in which all of the staples must be of such size as to extend through the finishing hoop and body.

A further object is to provide a riddle which can be quickly constructed and the parts of which when once assembled will not come apart.

With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claim.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a perspective view of a riddle embodying the present Fig. 2 is an enlarged section through a portion thereof. Fig. 3 is a section on line 00-00, Fig. 2.

Referring to the figures by characters of reference, 1 designates the inner rim of the riddle and 2 designates a metal fabric which is spread over the inner rim and has its edges bent thereover. These edges of the fabric are interposed between the rim 1 and a finishing hoop 3, and short staples 4: are driven through the hoop 3 and the fabric tenedztogether and to also prevent thewire.

fabric from pulling out of position. As an additional means for fastening the parts longitudinally arranged elongated staples 5 are driven through the finishing hoop 3 and through the edge portion of the fabric 2 and the inner rim 1, the ends of these staples being bent over or clenched as shown at 6 in Figs. 1 and 3.

By constructing a riddle in the manner described it becomes possible to provide means whereby all of the parts can be assembled before any of the fastening means are driven, and therefore one of the operations heretofore necessary is eliminated and the entire fastening process conducted in one operation.

Heretofore riddles have been constructed by fastening the finishing hoops to the inner rims by means of clenched staples. It has been necessary with this construction to clench every staple. With the present construction, however, a large number of staples may be utilized for fastening the finishing hoops to the riddle but it is not necessary to clench all of them because the finishing hoop is prevented from working loose from the inner rim by means of the elongated staples 5 which extend through the inner rim and are clenched. As these supplemental staples are few in number the operation of assembling the parts where only a few staples need be clenched is greatly simplified and is advantageous particularly when the riddle is manufactured by machinery. Moreover, by arranging the staples in the novel manner shown and described each supplemental lon itudinal staple not only serves to positive y engage and secure the metal fabric but also hold one of the smaller staples in engagement with the fabric so that it can not be withdrawn therefrom. This results in the fabric being securely held in place even though some of the staples 4 should work loose and drop from the riddle.

It is of course necessary to fasten the fabric at close intervals and therefore a large number of staples are necessary for this purpose. By arranging the parts in the manner described comparatively small staples can be driven through the outer hoop of the fabric for the purpose of holding the fabric in position, whereas only a few of the larger and more expensive staples These. staples.

need be employed for securing the finishing hoop to the body, these larger staples being clenched as shown and described.

What is claimed is:

A riddle comprising an inner rim, a metal fabric thereon having its edge portions extending therearound, a finishing hoop extending around the inner rim and the edge portions of the fabric, a set of fastening devices extending through the finishing hoop and the fabric and partly through the rim, said devices being disposed transversely of the finishing hoop, and a set of supplemental fastening devices extending through the hoop and fabric and through and clenched upon the rim, said last mentioned devices be ing disposed longitudinally of the hoop and extending across and constituting retainers for the first mentioned fastening devices.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two Witnesses.
